Project Info

Overview
The project re-built the I-5/US 12 interchange at Grand Mound to improve mobility and safety. The modified interchange configuration of US 12 over Interstate 5 eliminated the loop ramps. Traffic signals were installed at both ramp intersections resulting in a typical "diamond" interchange configuration. On the east side of the interchange, the two existing exits from northbound I-5 are consolidated to one exit point.

How you benefit

Improves safety
The project realigned and lengthened on- and and off-ramps at the interchange to provide the more room for vehicles to safely enter and exit the highway. The project also added signals and improved driver sight distance.
